What concentration of Cl2O remains after a mixture that initially contains [H2O] = 1.00 M and [Cl2O] = 1.00 M comes to equilibrium at 25 °C ? Kc for the reaction is 0.0900.

Equilibrium concentration of   is 0.870 M.

Explanation:

Initial concentration of water =

Initial concentration of

initially

1.00 M            1.00 M                      0

At equilibrium

(1.00m-x) M   (1.00-x)M                  2x

The expression of equilibrium constant is given by :

Solving for x :

x = 0.130

Equilibrium concentration of  :

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
